If a manufacturer designed a system that could be retro fitted to existing cars then I would have thought there would be additional environmental benefits in reducing the emissions caused by new car manufacture - even if performance wasnt quite on a par with a purpose designed vehicle.

My suspicion is that the main 'driver' here is about extracting as much money from our wallets as opposed to helping Madonna and the other celebs save the planet. Just watch those tax and other benefits evaporate if alternatively powered cars are bought in any great number.

I cant quite grasp why electro power is taking so long to develop, after all the Germans were producing efficient and powerful U boats at the end of the war (too late to see meaningful service) that used internal combustion engines in combination with batteries that were very advanced.

Just a thought.............
